Like I mentioned previously, not sure how I feel about Adeline coming back especially with her abilities restored. I guess Juliette having feelings for the Captain is more dramatic, but thankfully the memory phase seems like it will be over after next week.

The Captain being a bastard Prince probably has been the black sheep of the family. And he's obviously rebelling against the royal families, he's probably using Nick to try and get his hands on the coins, the key, the paper containing the burial site for the items of power the Grimm's hid.
